Equation for Reaction Between Baking Soda and Vinegar

Equation for Reaction Between Baking Soda and Vinegar The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects. Here is a look at the reaction between baking soda and vinegar and the equation for the reaction. How the Reaction Works The reaction between baking soda and vinegar actually occurs in two steps, but the overall process can be summarized by the following word equation: baking soda (sodium bicarbonate) plus vinegar (acetic acid) yields carbon dioxide plus water plus sodium ion plus acetate ion The chemical equation for the overall reaction is: NaHCO3(s) CH3COOH(l) → CO2(g) H2O(l) Na(aq) CH3COO-(aq) with s solid, l liquid, g gas, aq aqueous or in water solution Another common way to write this reaction is: NaHCO3 HC2H3O2 → NaC2H3O2 H2O CO2 The above reaction, while technically correct, does not account for the dissociation of the sodium acetate in water. The chemical reaction actually occurs in two steps. First, there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 HC2H3O2 → NaC2H3O2 H2CO3 Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas: H2CO3 → H2O CO2 The carbon dioxide escapes the solution as bubbles. The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it. In a baking soda volcano, detergent usually is added to collect the gas and form bubbles that flow somewhat like lava down the side of the volcano. A dilute sodium acetate solution remains after the reaction. If the water is boiled off of this solution, a supersaturated solution of sodium acetate forms. This hot ice will spontaneously crystallize, releasing heat and forming a solid that resembles water ice. The carbon dioxide released by the baking soda and vinegar reaction has other uses besides making a chemical volcano. It can be collected and used as a simple chemical fire extinguisher. Because carbon dioxide is heavier than air, it displaces it. This starves a fire of the oxygen needed for combustion.

Subject Lines, Subscriptions and Submissions Subject Lines, Subscriptions and Submissions Subject Lines, Subscriptions and Submissions By Maeve Maddox In this post I want to deal with some miscellaneous questions that have come to me via email. Subject Line Several readers have asked if I could put the days topic in the subject line of the subscription feed. I regret that the answer is: I cant. The way that the subscriptions are handled (Feedburner) does not give me the option of entering a post-specific description in the subject line. If it ever becomes possible, Ill do it. Subscriptions Every so often I get a request to enter a subscription for someone or to change an address. The subscription links are at the upper right-hand corner of the DWT page. Any address changes have to be made by the subscriber. Submissions Now and then writers ask about submitting articles or stories to this site. Language-related posts DWT does accept guest posts that conform to the following guidelines: 1. The post must be original. 2. The post must be related to the English language or writing in general (e.g., grammar, punctuation, freelance writing, writing exercises, etc. 3. The author must grant DWT the exclusive rights to publish it online. It may not be republished on the writers own blog or in an ebook. The writer does retain print rights. 4. Guest posts will include a byline with a brief bio about the author and up to two links (one for a website and one for a Twitter/social networking account). Submissions for guest posts may be addressed to daniel@dailyblogtips.com Fiction submissions Apart from contests, DWT does not publish fiction. Because so many readers are looking for a chance to publish their fiction, Ive decided to keep my eye open for possibilities. I just heard about a literary magazine that is looking for submissions. Although published under the auspices of an Arkansas college, it is open to writers from anywhere. VISIONS: literary magazine published online by Northwest Arkansas Community College. No payment, but for a writer building a portfolio, that may not be a deterrent. Want to improve your English in five minutes a day?
